The news came just weeks before Schwartz was scheduled to have a potentially life-saving stem cell transplant at the Seattle Cancer Care Alliance. The procedure was set for Aug. 27, and two “five-out-of-six” cord blood matches had been located for Schwartz. But now the timeline will change; Schwartz will undergo additional chemotherapy, as she must be in remission in order to have the transplant.

First diagnosed with acute myeloid leukemia in December 2008, Schwartz underwent 130 days of hospitalization before being released in May 2009. Eleven months later, the 22-year old learned that her cancer had appeared again, and she entered chemotherapy for the second time in April.

From that point forward, Schwartz’s family, friends and teammates, along with members of the Yale community, worked to find a donor for Schwartz through an extensive publicity campaign, which included a bone marrow drive at Yale on April 22.

A spokesman for the Seattle hospital where Schwartz was scheduled to have her transplant told the News on Tuesday that two cord blood donors had been located, but that the date for Schwartz’s procedure was liable to change depending on her condition.
